I
had a problem the other day reinstalling Quickbooks for a customer. The
program would not open and when I tried to reinstall it and an error
appeared about not being able to overwrite some files in the CONFIG.MSI
folder. Let me explain what the CONFIG.MSI folder is, where its
located, and if you can remove it safely.
First of all, the
CONFIG.MSI folder is a hidden folder on the root drive of Windows,
usually Drive C. The folder is used by the Windows Installer process
during an installation of software. It saves files with the extension
of .RBS and .RBF. These are Rollback Script Files used by the installer
to uninstall recent changes if an install fails somewhere along the
way. The rollback script file (.rbs) is always stored in the Config.msi
folder on the disk where the operating system is installed. The .rbf
files are stored in the Config.msi folder located on the disk where the
program that is being backed up currently resides. These can be two
different drives. |

Can the CONFIG.MSI folder and its files be deleted safely?
Essentially
the CONFIG.MSI folder contains backups of files that are being
installed or updated during a program installation. Upon a successful
completion, this folder and files are deleted automatically. However,
sometimes the installer program fails to remove these files. In this
case, you may safely delete the CONFIG.MSI folder and files from your
hard drive. Follow the steps below to access and remove the CONFIG.MSI
folder. Reboot the
computer and try to download Windows Updates, if they still fail to
install, continue with the next step.
